T) T '1 it reed a tine Application filed January 10, 1910. I Serial No.537,129-

I To all whom it may concern:

Be it known that I, LoUrs I. BERKOWITZ, a citizen of the United States.and resident of Boston, in the county of Suffolk and State ofMassachusetts, have invented new and useful Improvements inHammock-Supports, of which the following is a specification.

This invention relates to a hammock sup port, and its object is toprovide an improved collapsible or folding hammock sup port of few partsand simple construction,

which when extended or set up will consti-,

tute a strong and rigid support, and which may be quickly and easilyfolded one part upon another in substantially parallel relation incompact form for storage or transportation.

In the accompanying drawings which illustrate certain embodiments of theinven tion.Figure 1 is a perspective view of the preferred form of theinvention set up; Fig.

2 is a side View of said hammock support shown in Fig; 1', illustratingthe manner in which it 1s folded; Fig. 3 is an elevation of one of thepairs of legs and leg brace of the hammock support shown in Figs. 1 and2, in folded relation Fig. lis a detail view in elevation showing theconstruction of the top of a pair of legs; Fig. 5 is across sectionalview through the top frame member showing in detail the construction ofthe bracket hereinafter described; Fig. (3 is a side view of a modifiedform of hanunoch support set up; Fig. 7 is an end view of the hammocksupport shown in Fig. 6: and Fig. 8 is a bottom view of one end of theharm moc; support shown in Figs. Sand 7 when folded.

Referring to the form of hammock sup port shown in Figs. 1 to 5inclusive. a repre- The form of securement herein shown consistsin'makmg the ends of the legs 5 with a slot 6 into which the plate 6 isset, and

connected by a bolt c sides of the piping b and the plate 5 holds I theplate in place. Each plate 5 is made with an aperture or eye If whichisadapted to pass over the screw aat the end of the top frame. A tubulareyelet '12 passing through the apertures 5 of each pair of legspivotally holds the legs together, and leaves an aperture or e ve forthe entrance of the screw a somewhat larger than the diameter of thescrew as best shown in Fig. sh, so that it can be slipped heel on andoff the screw. A. thumb nut- (f is provided for each screw (1 to clampthe. plates 7) at the tops of the legs to the top frame a as shown in 1.Each leg'li is also connected with the top frame member a by a diagonalbrace c pivoted at .one end to the leg as shown at a. and to the topframe at 0 The detailed construction of the pivotal connection betweenthe braces c and the top frame a is best illustrated in Fig. 5. itbracket (Z secured to the top frame a bva rivet J" is made with twodownwardly projecting ears The braces c are provided with holes throughwhich the bolt 0* passes. said holes being sutiicientlv large to permitthe braces not only to swing on the bolt in a plane perpendicular to itsaxis but also to move laterally with relation thereto. Between thebraces c is a hollow cylindrical or tubular sleeve a which serves bothas a spacer between the ends of the braces c and also as a pivotal.support for the hook /z from which the hannnoclvi ll is suspended. Abrace is provided between the. legs of each pair andis piivotallj.connected at one end 'to one leg as snown at and detachahlv sccuredtothe other leg at its opposite end by means of a diagonal slot in which astud on the leg Z) is seated when the device is set up. A thumb screw 0*on the stud e clamps the slotted end of brace c to the leg 5. When thehannnock support is to be collapsed or folded. the screw 6* of each pairof legs is removed and the braces c folded upon leg Z) as shown in'Fig.3, and the two legs of each pair folded together assist shown in Fig. Asalready described. the braces 0 are allowed some lateral p y, and willswing toward each other on the bolt 0 when the legs are closed together.The nuts a are then removed and the eyes at the tops of the legs areslipped off from screws a and folded inward upon the topframe member a.Fig. 2 shows one pair of legs completely folded,-and the other pair inthe process of being folded. Thus, all the parts of the structure,namely, the top frame, legs and braces may be folded one upon another inapproximately parallel relation and in compact form for storage ortransportation.

In the form shown in Figs. 6, 7 and 8 the top frame member and the legs,instead of bein made of piping, are made of angle metal." \Vhenthis formis used the brackets 03 are preferably secured on the under side withinthe channel of the angle metal by bolts d, instead of extending over thetop of the bar as shown in Fig l. The pivotal connection between theupper ends of the legs of each pair, in this form of hammock support,and the connection between the tops of each pair of legs and the end ofthe top frame member, instead of consisting of'two plates, one securedto each leg, consists of the single plate f. The legs are pivoted to thelower (part of the plate f by rivets or bolts f an the extentof thespread of said legs is limited by the inclined edges f of the plate,which engage the side webs of the channel iron legs, the edges f of theend webs of the legs being beveled or inclined to permit the legs tobespread. In the upper part of plate 7 is an aperture or eye f adaptedto slip on and off the screw a at the end of the top frame member. Inother respects the construction of this form of hammock supportis thesame as that illustrated in Figs. 1 to 5 inclusive, and the method offolding and extending the device is the same.

I claim: v 1. A hammock support, comprising a top frame member having ascrew projecting from each end, a pair of legs at each end adapted to befolded to ether, a plate secured to the upper end of each leg providedwith an aperture adapted to slip over said screws, nut-2; to hold saidplates 1n place in said screws, and braces between said top frame memberand said legs, pivotally connected thereto, whereby the ends of the legsmay be disconnected from the'.top frame .member and all theparts of thestructure folded one upon another.

2. A hammock support, comprising a top frame member having a. screwprojecting from each end, a 'air of legs at each end adapted to be foled to ether, 2. plate secured to the upper .end 0 each leg provided withan aperture, a tubular pivot member or eyelet ivotally connectin theaerturesof P g P the two plates of each pair and adapted to bracesbetween the 'top frame member slip over said screws, nuts to hold saideyelets and plates in place on said screws, an
